New Crime-Fighting Tools Aim To Deter And Nab Terrorists
Fingerprints, ballistics, DNA analysis and other mainstays of the forensic science toolkit may get a powerful new crime-solving companion as scientists strive to develop technology for "fingerprinting" and tracing the origins of chemical substances that could be used in terrorist attacks and other criminal acts. That's the topic of the cover story in the current issue of Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, the world's largest scientific society.
Bethany Halford, C&EN senior editor, focuses on an emerging field known as chemical forensics, where the goal is to use the technology of chemistry to trace weaponized toxic substances and related materials back to their source. A chemical forensic analysis could, for instance, show that ingredients in a terrorist's weapon were produced in a specific factory. Criminal investigators then could check sales records to determine exactly who purchased those ingredients.
